Stock futures retreated at the end of a volatile week hit by fears about lofty technology valuations and aggressive artificial-intelligence spending plans.
The three main U.S. indexes are on pace for their worst week since April, when President Trump's tariff war roiled markets. The Nasdaq Composite is leading losses, down 3.6% through Thursday.
Investors' anxieties have dinged high-flying tech stocks and other assets seen as risky, such as bitcoin. Among those hard hit are crypto exchange Coinbase and chipmakers Micron Technology and Advanced Micro Devices, all of which have lost more than 16% this week (more on AMD).
Bitcoin slipped below $83,000, down more than 30% from its October high. The Cboe Volatility Index, Wall Street's fear gauge, touched its highest level since April this week and topped 27 on Friday.
Global chip stocks, including TSMC and ASML, sold off, weighing on country indexes. Benchmarks in China, Japan and South Korea lost more than 2%.
In recent trading:
--U.S. Treasury yields dropped well below 4.1%.
--Oil futures fell 2%, as the Ukraine-Russia peace appears to be progressing.
--The yen strengthened after Japan's cabinet approved a $135 billion economic stimulus package.
